Hello all,
I have a 97 Millenia that blows cold air even when the thermostat setting is set to 90. Need to narrow down what's causing the problem and if it's a DIY repair.
No visible coolant leaks in the inside of the car that would suggest a bad heater core; both heater hoses entering / exiting the heater core to the engine are hot suggesting coolant is flowing thru the core; no issues with car over heating from a bad thermostat. I've heard of blend door acuators failing or sticking but I don't have a clue of where it's located on engine side or under dash panel near the core. Given all other things are fine, could the blend door be my issue? Has anyone experienced this before? Appreciate any feedback....thanks!
